Ebinur Lake Wetland vegetation coverage in response to a micro-climate change

The normalized difference vegetation indexes (NDVI) for different years (1998, 2007, 2011, 2014) were extracted through a dimidiate pixel model for The Ebinur Lake Wetland, and combined with high accuracy field investigation data analysis. By using the NDVI index to calculate vegetation cover conditions in the study area, we analyzed temporal and spatial characteristics and the causes of variation, and established a linear regression model between vegetation and climate change. The results showed that: 1) In the spatial analysis, the highest level of vegetation cover was in the southwest of the alluvial plain, the level of vegetation coverage in the northeast was slightly lower than that in the southwest, and no coverage and low coverage grade areas were distributed the most widely. In the temporal analysis, no coverage areas were in a downward trend, low coverage and middle coverage areas increased, and higher coverage and high coverage areas were in a downward trend; 2) In response to climate change, there were certain differences in different vegetation coverage levels. The degree of reaction of vegetation coverage to rainfall is the strongest, with hysteresis, at certain times, and showed no obvious response to air temperature. Between humidity and vegetation coverage level there was a completely concat relationship.
